To all whom it may concern.V

Be it known that I,.-'FRANK E'.'HARE, a citizen of the United States, and a resident of Boothbay Harbor, in the county of Lincoln and State'oi Maine, have invented a.

new and Improved Starting 'and Stopping Device for Phonographs, of which the following is a full, clear, and exact description. 'y y The invention relates to phonographs using disk records, and its object is to pro- 1 vide a new and improved starting and stopping device i'or such phonographs and similar machines` and arranged to enable the user of the machine to` readily start the same and to permit of conveniently and quickly setting the device according to the record with a view to automatically stop the machine at the time the stylus reaches the end of the groove in the record.

In order to accomplish the desired result, use is made of a stopping means to .stop and release the` turntable of the phonograph, a swing arm extending over the turntable andv the record held'thereon, the swing arm being manually-controlled to allow of setting the swing arm in any desiredposition relative to the record, and .,a. controlling means mounted on said swing arm and connected with the said stopping means, the said controlling means bein manually controlled for releasing the said stopping means to start the phonograph, and the Asaid controlling means being adapted to be actuated by -f'- any approved construction the stylusonythe sound box of the pho-nogra-ph to release 'the said stopping means, anld thereby'stop the phonograph automatica y.

A practical embodiment` of the invention is represented in the accompanying drawings forming a part of this specication, in which similar characters of reference indicate correspondin parts in all the views.

Figure 1 isa slde elevation of thestarting and stopping device as applied to a phonograph, parts being shown in section; Fig. 2 is a plan View of the same; Fig. 3 is an enlarged inverted plan View of the swing arm with its pivot shown in section; Fig. 4 is a cross section of the same on the line 4.-4 oFig. 3; and Fig. 5 is a perspective view of the brake for the turntable.

The phonograph on which the starting and stopping device Ais applied may be of f. a suitable frame or casing 1n which is jourand mountedv on/ in a handle L under the control of the optable C supporting the disk record I), in the groove of which is adaptedto travel the stylus E of the soundbox F for repro ing the sounds fin-the usual manner.

horn or other means for delivering the reproduced sound into arooin are notnshown proved construction so that further descrip: tion of the same is not deemed necessary. v

leasing., the turntable C or forstopping the saine is arranged as follows:, 0n the top `of the frame or casing A is mounted a spring brake G having a shoe G', of leather,

engage the under face of theI turntable C to hold the same normally against rotation. The free endof the spring brake G is proon the under side of a swing arm I having a hub I Vmounted to turn on a, pivo the top of the frame or casing A by "score/ws J2 screwing in the frame of the casingA passing through elongated slots J arranged in theplate J, as plainly shown in Fig.. 2. The arm I extends over the turntable C and the disk record D held thereon, and the said swing arm I can be moved into any desired position by the operator, and in order to hold the swing arm I in the adjusted position use is made of a spring K coiled on the lower end of the pivot J and engaging the under side of the hub I. The upper end of the hub I is engaged by the head of a screw the hub I in contact with the ,spring 'K with a view to increase or decrease the tension thereof and tp thus hold the swing arm the operator. l

The under side of the swingl arm I 1s providedfwith spaced'bearings I3, Il in which is 'mounted to slide a rod L of spring wire or other similar material. The rear end ot the rod L is provided with a depending ofiset L engaging the upper end H3 of the tripping lever I-I to impart a swinging more ment to the same on pulling the rod L iorward, so that the spring brakeG releases the turntable C to allow the latter to rotate. The' forward end of the rod L terminates duc-z The y,

'ifio Near the forward end of the rod L is adjustably secured a. block N by the use of set screwsO, and from the vblock N extends sidewise an arm N onY which is adjustably secured a head N2 by the use of aclamping screw N3, theouter edge being approxivmately ofa curvature corresponding to the shape of the last convolution of the groove in the disk record, as .plainly indicated in Figs. 2 and 3. The outer edge of the head N2 is adapted to be engaged by the stylus E so that the latter imparts a swinging motion to the forward end of the rod L at the time the stylus reaches the end of the groove in the disk record D. The arm N is guided on aV guide rod P attached to the swing` arm I, the guide rod P also serving as a stop for limiting the `inward movement of the stylus toward the centerof the disk record'D. On the block N is adjust-ably ecured a sidewise extending stop plate'Q ly the use of set screws Q', and Vthis stop plate Q is adapted to abut with its inner edge on the forward end of a stop plate R adjustably secured by screws I2. to one side of the swing arm I, the screws R passing through an elongated slot in the stop plate R to allow of adjusting the latter lengthwise on the swing arm I.

The operation is as follows: After the disk record D has been placed in position on the ,turntable C the operator swings the swing arm I over the disk record to a point near the center of the record, and then the operator pulls on the handle L2 so that the v brake G releases the turntable C to allow the latter to rotate driven by the usual motor of the phonograph. The operator then swings lle arm I outward until the outer edge of the head N2 is at the last convolution of the spiral groove in the disk record D, as plainly indicated in Fig. 2. On pulling the rodv L forward as above described the inner edge -pf the plate Q moves into engagement with the forward end of the stop plate R to hold the rod L locked in its forward position for the time being. When the piece. has been played in the usual manncr'and the stylus E reaches the innermost convolution of the groove inthe disk record D then the .said stylus engagesthe head N2 and pushes the .same toward the arm I whereby. the plate Q moves out of engagement with the stop plate R'thus unlocking the rod Land allowing the same to move rearward owing to the action of the springof the bra-ke G imparting areturn swinging movement to the. tripping lever H. It will be noticed that when the rod L is released and-with'it the tripping 1ever H, the brake G returns to normal posi- -tion, that is, its brake shoe G moves into Contact with the under face of the turntable C to stop the latter. l

From the foregoing it will be seen that by the arrangementdescribed the brake G for the turntable C'is manually released at the time the rod L is drawn forward by the operator, but the brake is automaticallyapplied by the action of the stylus E on the head N2, as above explained. v The starting and stoppin@ device shown and described is very simple and can be readily applied to phonographs and similar machines, as now constructed', -and the swing arm I can be readily set according to the rec- 0rd used and irrespr-itive of theradial distance from the-end of the groove tothe cen-f ter of the disk record.v It willalso be noticed that the arm I can be set relative to the d islr record at any point intermediate the beginning and the end o fthe groove to automatically stop the machine .at the time the stylusl reaches. such point.

The sweep of the swing arm I is preferably somewhat less than that .of the reproduoer arm and in order to insure that thestylus E strikes the outer edgeof the head N2 approximately at the ,same point each time the machine is used, it is necessary to set the center of the pivot J slightly to the right of a radial line extending from the verp tical axis of the reproducer arm to the center of the turntable C. f
